1 Claim.

The invention relates to a lamp protector and more especially to an electric lamp guard of the reflector type.

The primary object of the invention is the provision of a guardof this character, wherein its construction is such as to enable easy application to a lamp of the electric bulb type or removal therefrom, the guard in its entirety being of novel construction and when applied will be locked securely.

Another object of the invention is the provision of a guard of this character, wherein the latching means for the securing of the guard in place upon a lamp is swingably connected to the body of the guard in a novel manner in that certain of the frame wires afford the pivotal arbors for the said latches.

A further object of the invention is the provision of a guard of this character, wherein the lamp bulb is assured against breakage particularly where the same is a part of a trouble lamp or an extension lamp.

A further object of the invention is the provision of a guard of this character, which is simple in construction, thoroughly reliable and efficient in operation, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred and modified forms of embodiment of the invention and pointed out in the claim hereunto appended. I

In the accompanying drawing:

Figure l. is an elevation of an showing the guard by full lines, constructed in accordance with the invention, applied to the lamp while by dotted lines the said guard is in a position for removal thereof from the lamp.

Figure 2 is a sectional view taken on the line 22 of Figure 1 looking in the direction of the arrows.

15 Figure 3 is a fragmentary perspective View of the guard showing a modification of latches, one of the latches being shown by full lines in latching position and by dotted lines in a releasing position.

50 Similar reference characters indicate correspending parts throughout the several views in the drawing.

Referrin to the drawing in detail, the lamp guard comprises a twopart circular clamping 55 ring, the parts 53 and 6 thereof being semicircular electric lamp frr or and of channeled strap formation, each providing inwardly directed flanges l and 8, respectively, with the internal channel 9 therebetween, while spaced the required distance from these parts 5 and 6 is a circular disk Ill being drilled or 5 therwise formed with holes accommodating loosely hook terminals ll of a plurality of wire members l2 for hinge connection of the same. with the disk. These members l2 are curved outwardly so as to incase an electric lamp bulb 10 i3 detachably fitted within an electric light socket part M as fitted within a grip handle 15.

These members iii are uniformly spaced apart and an even number thereof at one side of the guard and similarly an even number at the other 15 side thereof are soldered or otherwise secured to semicircular framing wires it and in this way creating separable halves to the said guard, which are adapted to swing toward or away from each other in the application and removal of the 20 guard in the use thereof.

The wire members l2 are formed at their ends remote from the hook terminals l i with inwardly directed coupling terminals Ill which are carried through notch clearances it in the flanges l of 25 the parts 5 and '5 into the channel 9 in each where these terminals are soldered or otherwise secured to the said parts Sand 6 for the joining thereof together.

The parts 5 and 5 joined with the wire mem- 30 bers l2 are adapted to be engaged concentrically about a reduced neck is formed on the handle 1 5 for the guard to incase the lamp bulb is and be carried by said handle.

The part 5 at diametrically opposite points 35 thereof has projected through openings 29 therein the outstruck cranklike bights 2i formed from certain of the terminals 5'! of the wire members l2. Swingably connected with these bights 2! a pair of inherently resilient leaf-like latch members 22 for snap latching engagement at the ends thereof with keepers 2 cut and struck the part 5. These latching members 22 fasten the clamping ring in place and securely about the neck 59 of the handle it: yet the guard readily releasable from the handle l5 when it desired to change or replace an electric light bulb It for fitting in the socket I i.

In Figure 3 of the drawing there is shown a slight modification of the invention wherein each latch is made from a single length of wire 25 having linkage at 25 with the bight 2i and formed in this wire 25 is a latching jaw 2? for engaging a keeper formation 28 as should be clearly apparent for the fastening of the parts 5 and t together in the clamping of the guard in place on the handle 15 for incasing the bulb l3.

The wire members [2 and the framing wires l6 produce in conjunction with the disk l0 and the parts 5 and ii of the clamp a cage involving separable parts.

What is claimed is:

In combination with a lamp guard of the class described and comprising a cage made in two separable parts, each consisting of a plurality of curved wires, a disk having the wires of the two separable parts hinged thereto, a two-part internally channeled clamping ring, the wires of one part of the cage being fitted to one part of the ring and the wires of the other part of saidcage being fitted to the other part of said ring, said parts of the ring having side openings adjacent to the ends thereof, the wires connected to one part of the ring and next to the openings in the latter being formed with outstruck cranklike bights in the direction of said openings, and latches swingably connected to said bights and separably engageable with the other part of the ring at the openings therein for the clamping of said ring about a holding member for the lamp and the fastening of the two parts of the ring together.
